Where Does Google Chrome Store Bookmarks

If you are signed into Chrome with a Google account and have enabled, your bookmarks are also stored on Google's servers. However, the local Bookmarks file remains the primary offline storage. When you add or remove a bookmark, Chrome updates both the local file and syncs the change to the cloud.

You rarely need to manually open the Bookmarks file. Use Chrome's built-in tools instead: where does google chrome store bookmarks
